开关电流滤波器设计的一种新方法

A New Method for Designing Switched Current Filters

通过典型实例，提出了开关电流滤波器的一种新颖的设计方法，该法遵循从 Ｒ Ｌ Ｃ滤波器到有源 Ｒ Ｃ滤波器，然后到开关电容滤波器，最后到不存在有限传输零点的开关电流滤波器的顺序进行设计，方法简单易行．由于 Ｒ Ｌ Ｃ滤波器的设计有表册可查。

A new method of switched current filter illustrated by a typical instance is proposed. The designing procedure is from RLC prototype filter, active RC filter, switched capacitor filter to switched current filter for the condition of limited transfer naughts\|free. Because the RLC prototype filter can be looked up in some related ready made handbooks, it is convenient to design many kinds of filters of various specifications according to this procedure and the method presented.\;
